Note that r.external is the analogue of r.in.gdal, which doesn't accept
any configuration options.
The analogue of r.out.gdal is r.external.out, which has an options=
option.
If options are needed for reading, a similar option should be added to
both r.in.gdal and r.external, presumably using GDALOpenEx() instead of
GDALOpen(). The latter will require extending the GDAL "link" format
(lib/raster/gdal.c).
